Velfac Bi-Parting Doors


At VELFAC we believe in light and air, and in windows and doors that create comfortable and beautiful buildings which encourage an excellent indoor climate – and that’s why we created the bi-parting sliding double door. Thanks to its unique construction, the VELFAC bi-parting double sliding door can create an extra-wide, uninterrupted opening of up to 2.5 metres*, ideal for kitchens, dining rooms or garden rooms. The composite frame design combines low maintenance, durable external aluminium with attractive inner pine, to enhance your property inside and out.

VELFAC sliding doors are available in two different versions:

Standard threshold: 70mm

Low threshold: 24mm

The VELFAC sliding door with low threshold provides the same beautiful slim profile, security features and high energy performance of his standard threshold version (75mm), and it is Part Q compliant.

Keeping it simple

The bi-parting sliding double door takes up very little space when open, also making it the ideal choice for narrow terraces or balconies – anywhere where space is at a premium.

The signature slim VELFAC frame design delivers a flat, seamless façade when the door is combined with other VELFAC windows, whether fixed or opening. The slim frame also improves energy efficiency meaning no cold spots, and full use of floor space right up to the glass.
